Leviticus 7:31-35

The Priest’s Part in the Offerings

³¹And the priest shall offer up the fat in smoke on the altar, but the breast shall belong to Aaron and to his sons. ³²And you shall give the right thigh to the priest as a contribution from the sacrifices of your peace offerings. ³³The one among the sons of Aaron who offers the blood of the peace offerings and the fat, the right thigh shall be his as his portion. ³⁴For I have taken from the sons of Israel the breast of the wave offering and the thigh of the contribution from the sacrifices of their peace offerings, and have given them to Aaron the priest and to his sons as their allotted portion forever from the sons of Israel.

³⁵‘This is the allotment to Aaron and the allotment to his sons from the offerings by fire to the Lord, on that day when he presented them to serve as priests to the Lord.
